T0 @ZZ whom t may concern:

. Be it known that LVWALTER E. CRANE, a citizen of the United States,residing at Hartford, in the county of Hartford andV State ofConnecticut, have invented certain new and 'useful Improvements inMachines for Proprior application for United States Letters rss Patent,Serial No. 509,985, filed May 3,1894. The principal object of my presentinvention isto provide improved means for successively formingcharacters in relief upon a printing-strip or other suitable sheet ofmaterial, one character at a time, this result being attained by meansof coacting complemen tary d'res mounted for independent radialmovements upon their carriers and oppositely rotative in synchronism,and having means for radially closing the dies upon the strip fromopposite sides thereof when the dies are alined in working position.

Another object of the invention is to so construct and organize theworking parts of the machine which control the operation of the diesthat in case two key-levers or-dieactuators-(which are indirectlyconnected with and which select and determine the movements of the diesto be brought into use) should be depressed or operated almost simultaneously, or one very slightly in advance of the other, the last oneso depressed will have no eiject .unless the operation of thefirstselected die shall have'been completed..

Another object of the invention is to provide an improved shiftablecarriage for supporting the material to be' operated upon, whereby acontinuous sheet of material of indefinite length may be fed betweencomplementary dies in position for being operated upon, and whereby dotsor cavities may be formed in one or both side edges of the strip toenable the same to be fed through the carriage of the machine, and to soform said dots or cavities that they may be subsequently utilized asguides or gages to facilitate print- Aing from said strip when the sameshall be used in connection with a suitable printingmachine for printingpurposes; also, to furnish in connection .with the carriage of'themachine improvedline-spacing mechanism, whereby the extent of saidspacing maybe varied as may be required. v

In the drawings accompanying and forming a part of this specification,Figure l is a plan View of a machine embodying my present im;provements, said machine being provided withA two sets ofdies arrangedfor simultaneous rotary movement about fixed axes and having means forcarryiu g the material to be operated upon between the two sets of dies.Fig. 2 is a side elevation of the machine as seen from the left hand inFig. 1.

My improved'lmachine for?. prod ucingA printing-snrfaces, in'thepreferred form thereoflierein shown and described,'coinprises twocomplementary coactin g sets of dies of cameo and intaglio type,respectively mounted for and to retain the same in said position untilan impression has been' made, and means in position and adapted forengaging and clos ing said two coacting complementary dies relatively totheir carriers when in working position) to form a character upon or inthemav terial held between said dies, all'ofwhich Will be hereinaftermore fully described.

The framework of my improved machine may be of any suitable constructionfor carrying the several operative details, it being herein shown asconsisting of the two sidel plates or uprights A and A',the main frameor head'of the machine, (designated in a gen-- eral way by B,) which issecured between said uprights, the front plate C, connected at its iupper end to the head B, near the central p0rtion of said head, by rods2 and 3, which rods constitute guides for the shiftable carriage,

as will be hereinafter described, and con-f nected near its lower end iosaid head by side plates C' 'and C", vand a stop-'carrying frame(designated in ageneral way by D) seo .cured between the side plates Aand A' -inthe i rear of the head B, as will be hereinafter described.

In the form thereof herein shown the main frame or head B istransversely recessed at its forward end midway of its hei ght, as shownat 4, forming practically two "forwardly-pro-v jecting parallel arms B'and B", sufficiently remote from each other to permit l.the passagebetween them of the strip of material (designated by P) to be operatedupon. The forward ends of these 'two arms are preferably vverticallyinclined toward a common center between the adjacent edges thereof, as

shown at 5 in Figs. 2, 3, and 6,the purpose 'of which will behereinafter described. Formed longitudinally through the head B are twohorizontally-parallel,journal-bearings 6 and; 6', respectively, locatedone above and the? other below the space 4, as most clearly shown inFig. 6 of the drawings. In these bearings are journaled two die-carryingshafts E and E', respectively, which shafts have secured to theirforward ends (one to each shaft) two complementary revolubledie-carriers F and F', respectively, which carriers have formed thereonor secured thereto the impression- -dies G and G', respectively adaptedfor impressing-characters in the strip" of in'aterial' to formprinting-surfaces. The two arms B' and B"of the headB will betransversely and lvertically recessed at their forward adjacent edges toreceive the die-carriers F and F. These die-carriers in the preferredform thereof herein shown are, and usually will be, in the nature ofwheels or drums, the rims of which. will preferably be constructed ofresilient metal slit transversely, as shown at f,

most clearly in Figs. 11, 12, and 13, to form a series of yieldingdiezcarrying arms 7.l

Formed upon or secured to the ends ofthe resilient armsof both carriersor drumsF and F' are dies 'G and G', the ones G Vupon the carrier Fbeing of cameo'construction and lthe ones G upon the carrier F' being ofintaglio construction, each die'of one carrier being complementary to orcoinciding with a die arranged in a coinciding position upon theadjacent carrier.

In the drawings, Figs.` 6, l11, 412, and'13, I have shown the dies asformed integral with the die-carriers, the resilient arms of saidcarriers F and F' being enlarged at their free ends 'and havingcharactersformed upon and in their adjacent faces, respectively. vItwill be understood, however, that I do not desire .to `limit myself toVthe particular construction of-dies and die-carriers shown in saidligures. These die-carriers are secured to their respective shafts 'so'that two coinciding dies, one o'f eachseri'es, will normally be indirect alinement and in close proximity to each other, suiicient spacebeing left between the dies to permit the free passage of the materialto be operated upon. Secured to the rear ends of the two die-carrier'shafts -E and E', are gear-wheels 8 -and 8', respectively, whichgear-wheels-'are lin intermeshing engagement and are adapted forintermittently rotating the two shafts,the carriers, and the diessimultaneously in synchronism and' at equal speed, so as toinsure'theconstant coincidence in position of complementary dies uponthe two die-carriers, so as to 'bring any two selected complementarydies into workin g position directly in vertical alinement between theaxesl ofthe -two shafts,it being understood that 'the successive dies ofeach setare radially disposed with relation to the axis of itsrespective carrier.. Y

As a means for preventing the resilientdiecarrying arms of the carriers(which in practice will betempered in the form shown in Fig. 6) frombeing bent. inward out of alinement owing to frequent vibrations duringoperation, I haye provided in connection rio [O to permit the entranceand operation of the' with each carrier a disk 14, which will preferablybe secured to the shaft of said carrier and which has a peripheralbearing against the inner faces of the die-'carrying arms, thusretaining said arms normally in peripheral a'linement and preventingthem from being sprung inward beyond their proper normal positions.

Asv shown in Fig. 6, the die-carriers are cupshaped, they being open attheir forward ends two die-operating members of slides H and H',respectively, which slides are fitted for sliding movement in slideways9, formed in the rear'faces of the two caps lO and 10', secured to thefront ends of the arms B'and B" of the 'head B, plates 11 and ll'beingsecured to the caps 10 and l'O'fat vthe rear of the slides H and H' nearthe inner ends thereof, as

shown, t prevent lateral movement of said slides during operation.These. slides Will preferably be curved at their adjacent ends, as shownat 12, to correspond with the curvature of the interior ofthedie-carriers, and each slide has afcentral die-engaging finger orprojection 13 yof slightly less Width than the width of vthe die itis tboperate, which finger terminates adjacentto the inner face of the diellocated in impression position, which die is the one to be operated.

.As a means for actuating the die-operating slides H and H', whichextend inward with their operating-faces terminating adjacent to theinner faces of two adjacent dies, as shown in Fig. '6, said slides arecarried at their outer ends'upon cranks 15 and 15',

formedupon the forward ends of rock-shafts l and I', respectivelyjournaled in the head Bi, one above and the other below thetwodie-carrier shafts,.as 'shown partially in full and partially indotted lines in said Fig. 6.

/Secured'to the rear ends ofthe rock-shafts I and l are rocker-arms Jand J', respectively,

whichA rocker-arms. are connected at their outer ends by connectinglinks or rodsK and 'K' to oppositely-disposed eccentrics or cranks 16and 16' upon a driving-shaft L', journaled in a bearing 17, formed uponan upright 18, secured to the frame of the machine, as most clearlyshown in Figs. 3, 5, andv 7 of the drawings.

The driving mechanism for rotating the die-carriers F and F' and forreciprocating the die-operating slides H and H comprises, in part, arevoluble driver or wheel L, loosely mounted for continuous rotationupon the tubular journal-'bearing 17, said driver being operativelyconnected with one of the die-carrier shafts, as E, by a frictional oryielding driving device, as `will be hereinafter more fully described.

As a means for stopping the rotation of the die-carriers at variouspredetermined points in their travel to insure the positioning of therequisite pair of dies for use I have provided, in connection with oneof the die-carriers, a stop mechanism, which, in the preferredfformthereof herein shown ,consists of avmultiplicity of pin-stops 20, whichcoincide in number to thenumber of pairs of dies employed. Thesepin-stops are herein shown vsupportedfor longitudinal movement in thefront and back plates 2l and 22 of the stopcarrying frame D and ashaving their an gu-f lar positions relative to a commony center covincident Withthe angular vpositions -of the These pin-stops ,a portionthereof upon a'rod 26 and a portion thereof upon arod 26', secured attheir ends in the side plates A and A of the machine. Each key-lever isprovided at its forward end with a suitable key 25, havingga'characterthereon to correspond with the character of the pair of dies Whosemovements said key controls, after. the manner 'of key-levers ofordinary type-Writers. 1t will be understood that the key-leverdescribed constitutes one of a series of key-levers, which correspond innumber to the number of pin-stops employed, all of which key-levers' areapproximately duplicates of'one another.7 Each key-lever is ynormallylheld up to its Working position by means of a suit-able spring 27,bearing against the forward end thereof,.and is adapted to independentlyactuate oneof the pin-stops just described, which pin-stop determinesthe positioning of one pair of dies. These pinstops are located aroundthe shaft E and are adapted to be shifted independently, with theirforward ends intersecting the path of travel of a radial stop-arm 28,secured to the shaft -E and adapted to rotate therewith, nas mostclearly shown in Fig. 4of thevdrawings.

.In the embodiment of my invention herein loo IIO'

shown the driving mechanism consists of the driver L, mounted upon thecylindrical bearing 17 and adapted to be continuously rotated by a belt(not shown) driven from any suitable\ source of power, a friction-wheel30, fixed to the die-actuating shaft or crank-shaft L', a cam 31,loosely mounted upon the outer,

end of the shaft L', driving-levers M and M', pivotally carried bythedriver and held in yielding contact with the cam 31, and a fric- SD, asmost clearly illustrated in Figs. 7 and 8 of the drawings. The driver Lis in the nature of a wheel recessed at one side thereof, as shown at17', to receive the frictionwheel and drivinglevers, aswill beunderstood by reference to said Figs. 7 and 8.

Loosely mounted upon the outer end of the die-closing shaft L' andpreferably formed integral with the cam 3 1 is a grooved lpulley 34,-which is connected bymeans of a belt (shown in dotted lines in Figs. 2,3, and 4ot` the drawings) to a similar pulley 35, connected withtion-band 33, adapted for engaging the wheel Y Jthe die-earner shaft E,whieh shea receives its motion through said belt and pulleys and thedriving mechanism hereinbefore mentioned.

In' the organization herein shown the cam 31, through the medium-ofwhich the 'carriershaft E is rotated and which controls the I movementof the Adie-closing shaft L', and

consequently -the reciprocatory movement of the die-actuating slides, isin the nature of a wheel carried on the shaft L' and having an offset orcam-'groove 31 formed inione face thereof, against which afriction-roller 32,

ipivoted to the working end of the lever M,

normally bears, said lever being held with the friction-roller inconstant engagement with the cam bymeans of a spring 36, secured to thedriver L and bearing at its free end against a laterally-projecting arm32' upon the opposite end of the lever M. The lever' M', which isoppositely disposed with relation to th'e lever M,is provided at itsinner end with a brake-shoe 37, which bears against the face of the cam31 opposite the point against which the friction-roller 32 of the leverM bears, said lever M' being also held in contact with thecam 31 by aspring 36', which bears at i'ts freeend against a` laterally-projectingarmf:7';npon lthe lever M'. This lever M', which is in constantfrictional engagement with the cam 31, has a4 tendency to continue therotation ofthe cam, and thereby will pre- Avent any backward movement orrebound of the cam after it has been stopped by the in-y terception ofmovement of the diecarrier.

This 'construction and arrangement of cam 1 and driving-'leversconstitutes a frictional 'stops 2O is thrown into the path of movementof the stop-arm 28 by means of one of 'the keylevers to position a pairof dies for use, as will be hereinafter described; Said stopping of thepulley 35 also stops the pulley 34and the ca1'-31,connebted therewith,which, ow-

ing tothe continued rotation of the driver L, causes the friction-roller32 of the lever. M to ride out of the cam-groove 31', at which time thefriction al"drivingbelt 33,which surrounds .the friction-wheel and isconnected t one end, as at 38, to the leve'r'M and at'its pposite endto-a blockI 39, connected, as hereiny afterdescribed, to said driver,is" brought in close impingement by the movement of said 'lever M withythe friction-wheel 3Q, which,

being ixed'to the power-shaft L', rotates said driving-shaft andvoperates, through the connections hereinbefore described, thedie-operating slides `H and H'. The shaft L is carried the distance ofone revolution at each operation of a key-lever, which brings thecam-groove of the'ca'm again contiguous to .the Vfriction-roller of thelever M, when` saidA lever immediately drops into the said groove,

releasing the friction-band from the wheel 30 and permitting the cam toagain rotate,with the driver. This operation takes place. at eachdepression of a key-lever, as will be hereinafter more fully explained.

By the foregoing it will be seen that the lever M has two functions-thatof assisting to rotate the cam that actuatesthe die-carrier and forintermittently actuating the die-closing mechanism-while the lever M'constantly tends to rotate said cam, which keeps the same, when stopped,up to its last position, to prevent backward movement thereof.

The pulley is fixed to a sliding member 40 of a clutch, herein shown asa pin-clutch,

`whichnnember 40 is loosely vmounted upon the die-carrier shaft/E and isadapted for engagement with a similar clutch member 41,

lfizred to the said shaft.

As a means for throwing the two clutch members into engagement one withthe other, so as to periodically rotate the die-carriers F and F', ashifter-lever 42 is provided, which is herein shown as hinged at itslower end at 43 to the frame of the machine and is provided with afriction-roller 44, which enters a groove 45 in a sleeve fixed to theouter end of the clutch member 40. This shifter-lever, in theiformherein shown, is provided at its upper end with a bifurcatedextension46,

which is pivotally connected therewith, as

shown at 47, and operatively engages a cam 48, secured to lthedriving-shaft L, the function of which cam will be hereinafter setforth. y,

As am'eans for throwing .the shifter-lever `or swinging'arm 42 inward ateach operation of a key-lever to throw the clutch members intoengagement and rotate the die-carriers IOO les

an actuator 49 is provided, which in thi'sjinl- Y stance is in the formof a rod supported ,for longitudinal movement in the frame vand havingat itsouter end a' hook 50 to engage the lower end or catch 51 of theextension 4 6 'of the shifter-lever.- This rod is connected at itsforward end with an operating-lever152, straddling the shaft of the feedratchetwheel for the carriage, hereinafter referred,to,which in turn issecured at its lower end to a shaft 5 3, extending transversely throughthey frame of the machine, and which is actuated byv levers 54 and 55,secured to the ends of'said rod and connected by straps or rods 56 and YVI Io 57 to 'a universal bar 58, extending transversely below thekey-levers of the machine in position to lbe operated by any one of.said

vkey-levers, as will be readily understood by a comparison 4of Figs. 1,2, and 3 of they drawings. The shifter-lever actuator 49 is nor-v mallypositioned with its hook in engagementwith the transversely-shiftablea'rm or extension 46 of the shifte1-.lever, as illustrated in Figs. 3and 4 of the drawings, the clutch members 40 and 41 being disengaged,but in position to be immediately shifted into engagement upon `thedepression'fof a key-lever.

The operation of the machine is as follows: Assuming the driver L andthe clutch member 40 as being rotated in unison, the `first resultsaccomplished by the depression of a key-lever are to simultaneouslythrow a pin-- stop into the path of travel of the stop-arm 28, securedto the clutch member 41, which Y is fixed to' the die-carrier shaft E,and to throw the clutch member 40 into engagement with the clutch member41, which startsthe rotation of the die-carriers. This rotation iscontinued until the stop-arm 28 comes in contact with the stop-pinselected and projected into the pathof travel thereof, which immediatelyarrests the rotation of the shaft E, stopping at the same time thepulley 35, the pulley 34, and the cam 3l, carried upon the power-shaftL'. This stopping of the parts just described leaves the pair of diesselected in position for forming an impression in the material supportedbetween said dies. The driver L, continuing its rotation, carries theend of the lever M out of the cam-groove in the cam 31, which tightensthe'frictiou-band around the friction-wheel 30 and causes said friction-Wheel, together with the driving-shaft L', to which it is xed,to'rotate, as before described, which operates the links K and K',which, through the medium of the rocker-arms J and J', rocks the shaftsI and I', to whichthe dieoperating slides H and H' are connected, thuscausing these slides to move toward each other and operate the dies thathave been positioned for use.

The actuating-cam 48 for the clutch-shifting lever is provided with twocam-faces and 61, the one 60 of which is peripherally disposed and firstacts lto throw the arm or extension 46 transversely of the shifter-leverwith its lower end out of engagement with the hook of the actuator 49,after which the cam-face 61, which is in the nature of atransversely-deflected flange, acts to throw the shifting-leverbackward, which carries the Clutch member 40 out of engagement with themember l41, leaving the parts-in position to be rotated when thefriction-band 33 is released from the friction-wheel 30, which occurswhen Vthe shaft L' has completed a revolutiou, as before. stated. Theextension or arm 46 of the shifter-lever is normally held in theposition shown in Fig. 4 by a spring 46', secured to saidshifter-leverand bearingat its free end against the lower end of the arm 46,- themovement of said arm 46 being limted by a' stop 46",'as shown in saidfigure.

The cam-faced iange 61 `is adapted to enter between the forks of the arm46, which prevents the accidental outward movement of the shifter-leveruntil the proper time for disengaging the clutch members 40 and 41 hasarri ved.

From the foregoing it will be seen that upon the depression of anykey-lever the two'complementary dies which are governed bythe pin -stopconnected with the key-lever depressed will be immediately carried intopo- 'ict between the two when the stopfis projected forward, which mightoccur if the stopsition for use, stopped, and then immediately pressedtogether by the operation of the slides all parts, excluding thedie-carriers, return to their normal position ready for operation whenanother key-lever is depressed, the dies being left in the position lastattained until the die-carriers are again rotated.

'H and H', after which they are released, and 2,7/0

Y 75 After the starting of the shaft L, which actuates the die-operatingslides, (the complementaryrdies being at this time in position for use,)the shifting-lever-aetuating cam acts to disengage the shifting-leverfrom the hook 8o of the actuator 49, this being accomplished by theperipheral cam-face b'O, which tips the extension 46 of theshifter-lever laterally, after which the cam-faced flange 6l acts tothrow said shifting-lever outward, carrying the clutch member 40 out ofengagement with the clutch member 41. The shifter-lever remains in suchposition after -disengagement from the actuator 49 that it cannot bereoperatedv by the actuator until the crank-shaft or power-shaft L' hascompleted a revolution. Th us it will be seen that from the time ofdisengagement of the shifter-lever from the hook of the actuator itcannot be again operated to effect the engagement of the clutch membersuntil the first operation has been entirely completed and theshifterlever assumes its normal position ready for engagement with thehook of the actuator and the said actuator-hook has attained its normali operative position due to the release of a keylever, after which saidshifter-lever may be again operated to rengage the clutch members.

The construction and organization just de- 'fof scribed is of materialimportance, as it insures the com pletionof -the'impression move-- mentof the parts and the return movement of said parts independent of therelease of the key-lever, also prevents the inauguration of thesemovements by the operation of another key until the completion of themove- -ments rst mentioned and the parts have returned to their normalinoperative position,

and also insures the retention of the type- Ym5 'carriers with theirselected dies in proper operative position until an impression has beenmade. Y, f The forward ends of the pin-stops will preferably be beveledor tapered, and the stoparm 28, which will preferably be in the'natureof a spring-arm, willY be likewise beveled at the face adjacent to saidstop-arm, so as to prevent any possibility-of injurious conarm should atthis time happen to be in aliilement with the pin projected.

The `carriage for supporting and v'feeding' thereof .herein shownconsists of the front and rear'plates 65 and 66, respectively, 'whichare remotely disposed and are connected to- Athe strip to be operatedupon in the-form '13 gether by suitable con meeting-rods, as 67 and .Y

67', said carriage being shiftably supported upon the guide-rods 2 and3, which extend through openings formed in the front and rear plates,as'ln'ost clearly shown in Figs. 9 and l0 of the drawings. Secured to orformed upon the rear plate 66 of the carriage is a horizontally-disposedfeed-rack 68, the teeth of which are in mesh with the teeth of a pinion69, secured tothe end of a shaft 70, journaled transversely in the headB. This shaft ,is provided at its-opposite end with a ratchetfeed thecarriage forward, as will be understood by reference to Figs. 2 and 3 ofthe drawings.

The ratchet-wheel 7l is shown in Fig. 3 as carried on the end of theshaft 70, and in order to permit the lever 52 to operate properly whilemaintaining a compact organization of the parts the lever 5 2is shown inthis gure as having an elliptical opening transversely of said lever, asillustrated in dotted lines, so that as the lever oscillates back andforth it may work in apath from one side to the other of Jthe shaft 70without interfering with the same.

. It willbe seenthat the connecting-rod K has approximately anelliptical movement. The downward movement thereof carries the pawl intoengagement with the ratchet-wheel, rotates the ratchet-wheel the properdistance- 'L'. e., the distance4 of one tooth-and carries the pawl outof engagement with said ratchetwheel, while the upward movement of saidconnecting-rod carries the pawl from its disengaged position upward atone side of 'the ratchet-wheel into position for rengagement with theratchet-wheel upon the downward movement of the connecting-rod. Thusitwill be seen that at each complete movement 'of the connecting-rod orcomplete revolutionl of the power-shaft L", which takes place at eachdepression of a key-lever, the carriage is fed forward the requisitedistance for the next letter to be impressed in the material carriedthereby.

The ratchet-wheelactuating pawl 72 is pivotally connected with theconnecting-rodv K' and is normally held in an operative position by aspring 7 3, secured to said connecting-rod and bearing at one endagainst the tooth-engaging end of-'tlie paowl, a stop 74 (see Fig. 3)being provided to limita the in" ward movement of said pawl. Thisresilient connection also prevents any liability of breakage in case thepawl should accidentally be brought in contact, when moved inward, withthe side face of a tooth of the ratchetwheel. The ratchet-wheel is heldagainst accidental movement and in position to be engaged by the pawl bymeans of a suitable spring 75, secured to the side plate A' of themachine and bearing at its free end between two teeth of theratchet-wheel, said spring constituting a detent-catch therefor.

As a means for actuating the ratchet-wheel independent of the movementof the shaft-L and connecting-rod K', as is desirable to feed thecarriage for spacing between words, I have provided a ratchet-actuatinglever 76, connected at its lower end to a lever 77 of a spacing-bar 78,which lever 77 is fulcrumed upon a shaft 79, journaled in the frameworkof the machine, the ratchet-wheel-actuating lever 7 6 being in positionfor engaging a tooth of and for rotating said ratchet-wheel at eachdepression of the spacing-bar 78, as will be clearly understood byreference to Fig. 3 of l the drawings, the spacing-bar being retractedin any usual manner, as by sprin gs, after each operation.

The pawl76 is shown herein as having its rearward movement limited by astop 76",

which is recessed at its forward side to form a guide for the pawl, andsaid pawl is also illustrated as pivoted to the' lever 77 and held upagainst the stop 76" by means of a spring 7 6', so that the pawl willhave a slight oscillatory movement,

In connection with the shiftable carriage I have provided an improvedline-spacing mechanism formoving the material forward therequisitedistance for spacing between f lines and have also providedmeans whereby the spacing may be varied as required. This line spacingmechanism, in the preferredv form thereof herein shown,:consists ofalpair of feed members connected for rotation in opposite directions andillustrated as two intermeshin g feed-wheels 80 and 8l and'apawland-ratchet feed-wheel-actuatin g device (designated in a generalway by S) in connection with and adapted for rotating said feedwheels.

In the construction and organization herein shown one of thefeed-wheels, as 80, has'a se-` ries of peripheral projections 80 and issecured to the rear end of a tubular shaft 82,

which has a bearing at its ends in the frontV andrear plates of thecarriage and surrounds the guide-rod 3, while i. the other feed-wheel 81has a series of peripheral indentations 8l to coincide with theprojections upon the feedwheel 8O and is revolubly supported upon acrank-pin 83 of a stud 83', journaled in the back plate of the carriage.Secured to the rear end of the stud 83 is a lever 84, by means of whichthe vfeed-wheel 81 may be thrown out of engagement with the feed-wheel80, as

lisrequired when inserting or removing a strip As a means for ofmaterial in saidcarriage. holding the feed-wheels in close intermeshingengagement a pawl S5 is provided, which is pivotally carried upon thelever 84 and is adapted for engaging the ratchet-teeth 86, formed in theside edge of an upwardly-projecting curved arm 87 of the back plate 66of the carriage. from engagement with these ratchet-teeth and theV lever8i is drawn to the left, as 'seen in IIO When the pawl 85 is'rele'asedfeed-wheel 8l with it in a substantially ver-v tical direction and th uswithdraw said feedwheel in practically a straight line from engagementwith the com plementary feed-wheel 80. Secured to the forward end of thetubular shaft 82 are two concentrically and ad jacently disposedratchetwheels 88 and 89, adapted to be engaged by a pawl 90, pivotallycarried upon a feed-iever 91, pivotally supported upon the shaft 82 atone side of said ratchet-wheels. These ratchetwheels have peripheralteeth to be engaged by the pawl 90; out the teeth of one ratchet-wheel,as 88, which will be herein termed the short-distance ratchet-wheel, area shorter distance apart 'than those of the ratchet-wheel 89, which willbe herein termed the long-distance ratchet-wheel. The short-distanceratchet-wheel usually has sixteen teeth, while the long-distance'ratchet-wheel has twelve teeth. The pawl for engaging these tworatchet-wheels is hereinfshown as a double pawl, or a pull-and-pushpawl7 it having two ratchet-wheel-engaging arms 90' and 90, one arm ofwhich is adapted for engagement with a tooth of the ratchet-wheel 88,and the other arm of which is adapted for engagement with a tooth of theadjacent ratchet-wheel 89. As ameaus for holding one or the other of thearms of the pawl 90 in engagement with one or the other ot' theratchet-wheels 88 or 89 a spring 92 is provided, which spring is securedto the feed-lever 91 and has an angular bearing-face 92 at its free end,which is adapted to bear at one or the other side of a pin 93 upon-thepawl 90 to normally hold one or the other of the arms of said pawl inengagement with one or the other of said ratchet-wheels, as will beclearly understood by reference to Figs. 2 and l0 of the drawings.

In practice the feed-lever 91 will be constructed. and organized to havea throw of sufficient length to accommodate for long or short spacing,abutments (not shown) being usually provided for this purpose. As ameans for limiting the throw of the feedinglever to accommodate forshort spacin g I have provided a stop 94, which is fixed bya screw 94 tothe front plate of the carriage in position to be engaged by one end ofthe pawl 90 when the opposite end of the pawl is in its workingposition, this stop limiting the retractive movement of the pawL andinsuring its engagement with the proper teeth.

In the form thereof herein shown y the notches of the ratchetwheel 88are divided into four groups of four notches each, there being one longand three short notches in each group, while the one 89 is divided intofour groups of three notches each, there being likewise two shortnotches and one long notch in each group. Hence it will be obvious thatI employ a pair ot' ratchet-wheels having each plurality of groups ofperipheral teeth, each 582,178A Y z of which groups embodies teeth ofvariable tween vseparate addresses, the short notches coutrollin g thedistance between lines of each address, while thevlong notches controlthe distance between separate addresses. This will be apparent byreference to Fig. 10, in

which it will be seen that the short notches of the ratchet-wheel 88 areof equal length and that two of said notches are of greater length thanthe one long notch of the group; also, that the two short notches of theratchet 89 are of equal length andthat the two, taken together, are ofgreater length than the one long notch of their group. The long notchesof the wheel 88 and the short notches of said wheel are also of lesslength than the correspondin g long and short notches of the wheel 89,and the two short notches of the wheel 8S are of greater length than onelong notch of the ratchetwheel 89, so that vwith a given throw of theactuating-pawls for rotating the ratchet-wheels, and which throw is justsufficient to reach the distance of one of the long notches oftheratchet-wheels 89, it will be obvious that-it will be impossible tograsp'more than one tooth at a time on either4 ratchetwheel, and hencethe arc through which either ratchet-wheel will be rotated is positivelyco u trolled without varying the throw of the pawl for actuating suchratchet-wheel.

In the drawings the feed-Wheels are shown as having one of them conicalprojections and the other conical indentations which form concavo-convexdots in the side edge of `the strip of material as it is being fedthrough the carriage, which dot-s constitute a traction-surface orfeed-rack for engagement with the feed-wheels to insure the advancementof the strip a predetermined distance -at'each intermittent movenient ofthe feed-wheels, said feed-dots also being adapted for utilizationasguides for the strip when the same is used in the carriage of thepresent machine or as feeding means when used in connection with avprinting-machine 'for printing purposes.v

The conical projections and indentations lupon the respectivefeed-wheels are shown in Fig. 9 as complementary, so that theimpressions formed in the strip will be in the nature IOO rio

of relieved projections having continuous surfaces, and theseprojections will not be punc- `tured or perforated, and hence thematerial of the strip will `not be weakened.

If desired, the .feed dots or indentations may be formed in. the' stripbefore strip is inserted'in the carriage.V u a The front andback platesof the carriage the said have oppositely and horizontally @disposedguiding-strips 95 and 96 connected therewith,

the one 95 bein g preferably permanently fixed to the back plate of thecarriage, as shown in VFig. 9 of the drawings,while the one 96 ispreferably pivotally connected with the front plate of the carriage,vasshown in Figs. 2 and 10. This construction and organization permit theprinting -st'ripto be removed from the carriage or inserted irrespectiveof its longitudinal position lengthwise of the carriage when thefeed-wheel 80 is thrown out of en-A gagement with the saidprinting-strip, which is very desirable for the purposes of correctionor change.

Each die-carrier in the acter-forming dies and one pair of blottingoutdies. The pairs of character-dies, as before stated, have each acharacter formed in relief and a complementary character in indent-ationadapted for forming a characterl in relief upon a strip of material,while the blotting-.out dies have plane faces and are adapted to bebrought into alinement each Yside the character `in the strip itisdesired to blot out and to be closed to press the strip into itsnormal lat condition and in condition to receive a reimpression, ifdesired, said blottingout dies being controlled in theirmovements by ablank key, (designated by N,) which key forms one of the series of keyshereinbefore described, the positioning and operation of theblotting-out dies-being substantially the same as the position andoperation of the character-formingdies, as will be readily understood byreference to the drawings andas 'more clearly described in my priorapplica tion hereinbefore referred to.
